HOLDER FOB CONCRETE1REINFORCING.

v Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed .Tannary 25, 1909. Serial No. 474,055.

To all whom it may concern:

Be it known that I, JOHN WESLEY REED, a citizen of the United States,and a resident of Hammond, in the county of Lake and State of Indiana,have invented a new and Improved Holder for Concrete-Reinforcing, ofwhich the following is a full, clear, and exact description.

The invention is an improvement in holdore for concrete reinforcing,such reinforcing, in the nature of bars, as is positioned along thewalls or floors of wooden forms during the course of erection.

In carrying-out the invention I construct the holder of a single pieceof wire, the

same being bent to form an eye to embrace the reinforcing bar, with theend portions of the wire extended from the eye to ro-- Vide nail prongs,the prongs being 0 set intermediate their length to provide strikingfaces, said nail prongs arranged to open the eye when spread apart,whereby the eyemay be sprung over the bar.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views. I

Figure 1 is a, fragmentary view of .a wooden form and reinforcing bar:with the bar held in position by my improved holders; Fig. 2 is avertical section through a form, illustrating the application of myimproved holders to hold the reinforcing bars in place, and Fig. 3 is aface view of the preferred form of the holder.

The holder, as shown in Fig. 3, is con-' structed of a single piece ofwire bent in- I termediate its length to form an eye 10 to embrace thereinforcing bar, the end portions of the wire being extended from theeye to :form nail prongs 11. These prongs have sharpened extremities andare outwa'rdly' offset intermediate their length to provide strikingheads or faces 12', by which the driving of the members into the woodenform may be facilitated. The holders described, as manufactured, havethe nail prongs l1 sprung apart in order that the eye. 10 maybe open topermit of its being passed over the reinforcing bar. These bars 13, asshown in: Figs. .1 and 2, are arranged along-the walls of wooden forms14, the bars being spaced from the inner faces of the walls, as is theusual practice.

In applying theholder as shownin Fig. 3 to the bar, the eye of theholder is passed over the body of the bar and the nail ,prongs forcedtogethercwith a pair of pliers or other suitable tool, closing the eyeto embrace the bar, as shown in Fig. 1. The nail prongs are then driveninto the reinforcing, either by striking the eye 10 or the offset orstriking faces 12 of the prongs. The holders are applied at suchintervals as are necessary to hold the bars agalnst displacement duringthe filling in of the concrete.

In testimony whereof I have signed my' name to this specification in thepresence of two subscribing witnesses.
